Applieatioii filed February 15,1912. Serial No. 677,665.

To all whom it may concern Be it known that I, Aucusro D. SAUMELL, a citizen of the United States, residing in New York city, borough of Bronx, in the county of- New York and State of New York, have invented certain new and useful Improvements in Sheet-Music-Perforating Devices, of which the following is a specification.

This invention relates particularly to means for producing perforated sheet music from the operation of a key-board, either from the usual keyboard of a piano during the playing of the same, or from a dummy keyboard; and also has reference to the means for producing the perforations corresponding to the operation of the pedals of a musical instrument.

One of the objects of the invention is to provide means for effecting a very rapid reciprocation of a punch member by the depression of a piano key or similar device for producing a practically continuous slot or opening in a music sheet or roll.

Another object of the invention is to provide means for causing perforations or marks on the'music sheet or roll from the operation of the pedals of a musical instrument.

A. further object is to provide the latter device with means for causing a single perforation or other indication when the pedal is depressed, and a similar perforation or mark when the same pedal is released.

In the accompanying drawings representing embodiments of my invention, Figure 1 is a fragmentary plan view of portions of a musical mstrument with my invention ap plied. Fig. 2 a detailed view, enlarged, in section. Fig. is a view similar to F 1g. 2

showing the relative size of the keyboard and the perforating mechanism. Fig. 4 is a detail enlarged of the levers operating the punches. Fig. 5'is a plan view of, the parts shown in Fig. 4. Figs. (5 and 7 show the levers for operating the punches. Fig. 8 is a v rtical section of a portion of ,the pedal engaging means. Fig. 9 is a section on the line (P4) indicated in Fig. 8; and Fig. 10 is a section on the line 10-10, indicated in Fig. 8. r

he device is shown as applied to an,0rdinary upright piano with a conventional form of keyboard; but this can be a dummy keyboard. The keys 12 may be simply the or- (linury key levers or any such device, and

beneath each key is arranged a circuit breaker of any suitable character, shown as comprising a spring plate 13 that is engaged by the key in its normal position, and when the key is depressed the plate is bent down to engage a terminal 14, another terminal being connected with the plate 13,

and these terminals by wires 15 and 16 form a circuit including a battery 17 or other source of electric power that will operate any suitable electric actuating device, when the key is depressed to closer.

A series of sheet perforators or punches are provided, and also an electromagnetic means, such as a solenoid 18, and core for operating each of the punches. Each of the.

solenoids will have its circuit connected with the circuits of the several keys to be closed thereby. As shown a common return 16 is provided connecting one terminal of the key circuit closer with the battery 17, while the individual wires 15 connect each of the plates 13 of the circuit closer with the respective electro-magnets, a wire 19 passing from each elcctrounagnet to the other terminal of the battery 17. Each solenoid 18 is shown provided with a core 20 that normally extends only partly into the solenoid,

and will be drawn in when the latter is energized, to compress a coil spring 2-1 therein, the reaction of the latter returning the "core to normal position when the current is broken for the solenoid.

Upon suitable means connecting each of the punches with the core-of the magnet, the punch will be advanced by depression of a key to close the circuit and energize that magnet. Means are also provided for interrupting the circuit of each magnet whereby upon the key being held depressed and the circuit retained closed thereby, the circuit will be rapidly broken to cause the rapid reciprocation of the core of the magnet, and consequently the punch will be given a rapid reciprocation, that will. serve to punch a series of holes in the paper as the latter is advanced; but the holes will be so close together as to form a n'uctically continuous slot, the length of which is determined by the advance movement of the paper during the depression of the key. As shown, a circuitbreaker is provided in the circuitpf each solenoid, comprising a spring lever 22 connected to one wire of the circuit, that normally engages a contact 23 connected to close the circuit v shown.

v eral operating levers far the punches,

the other wire of the solenoid circuit. A pin 24 is carried by the core 20 and when the core is drawn into the solenoid, this pin will strike the lever 22 and cause it to leave the terminal 23 and break the circuit of the solenoid. The latter will at once deenergize the solenoid, permitting the coil spring to return the core to normal position. This latter movement will release the lever 22 and again close the circuit.

very rapidly interrupted and produce a quick reciprocation of the core.

The means for perforating the sheet or roll is shown as comprising a stationary curved plate or tube 30 provided with scries of holes 31 therein preferably arranged in line. A bar 32 is arranged above the line of holes 31 and has bores therein in which reciprocate punches 33, each alining with and arranged to enter one of the holes 31 when advanced, but normally held a short distance away from the plate'30 by springs 34 that will return them when advanced. A shaft or rod 35 is arranged. at one side of the bar 32 and parallel therewith, and on which shaft swing a series of levers 36, shown'separately in Figs. 6 and 7. These levers have one arm at extending over to engage each of the punches 33 to advance the punches when the levers are swung.

For convenience is assembling the solenoids in close proximity to engage the slivt ey are arranged in rows ith the axes of the solenoids of each row radiating from practically a common point, or in other words arranged in the arc of a circle, and in several adjacent rows, as indicated in Figs-1 and 2; but being in somewhat staggered relation. The solenoids are allmounted on a curved plate 37, and the cores 20 of the solenoids are connected with the arms I) of the levers 36 respectively, by rods 38. It will be observed that'the adjacent levers have their arms a and b at different angles, to accommodate the different angular positions of the adjacent solenoids. It will now be understood that when any key is depressed the circuit closer lever 13 will close the circuit including wire 16 and one of the wires 15, and one of the solenoids. The core of that solenoid will be drawn in and the lever 36 swung to advance thecorresponding punch, that will pass through the web lV drawn over the plate 30 by any suitable means, not But the advance of the core will cause the spring plate 22 to open the circuit whereby the core is returned and also the punch. The circuit interrupter willat once close the circuit again, causing the current to pulsate in the solenoid and produce a rapid reciprocation of the core and hence of the punch. The successive advances of the punchef'j as the paper is advanced at a uni- By this means the circuit for the solenoid will be form speed, will produce perforations in the Inediately upon the key being released this circuit will be opened and the punch retracted.

In Figs. 8 and 9 a pair of pedals S and H are shown that are the ordinary hard and soft pedals for the piano or other instruincna The same mechanism to be now described, is applied to each of these pedals, and the description oi" one of them only will be given. For the pedal S is a lever 40 that extends between tern'iinal portions ll and 42 of the pedal, which portions are insulated from each other and connected with wires a3 and. 44-, respectively. As shown in Fig. 8, the pedal is in its normal raised open position at the outer end, with the lower end depressed as indicated at the right in his 10. In this position the terminal. portion of the pedal will ensagc with the lever that is pivoted at an by suitable insulat. means. When the pedal S is depressed my the foot, raising the inner end to the position indicated at the left in Fig. 10, the

minal 4-1 will disengage the lever and theten minal 42 will strike the lever 40 and shift the lever to the position indicated in Fig. 10, during which moment the terminal a1 is cut out from the lever ll). A termii member is provided that will connect wit the lever 40 at the intermediate portion of this movement, but which will not engage at the upper or lower position of the lever 40. As shown the terminal 45 is provided in the form of a button that will engage a terminal portion 1-6 on the lever, the terminals 45 and 46 being engaged at the intermediate portion only of the lever movement, but free therefrom at the two extreme positions, as indicated in Fig. 10 on each side, 'respectively..

For each of the pedals a pair of solenoids are provided, solenoids a7 and i8 being con nected with the terminals 43 and s4, respectively, while the terminal 45 :t'orinsa common return from the battery to said solenoids, hence when the pedal S is in its normal position, as shown in Fig. 8, neither of' these circuits will be'closed; but upon the pedal being closed, the inner end will be elevated and the terminal portion 42 will strike the lever 40 and elevate the lever. During this latter movement the button on the lever will engage the terminal 45 to completethe circuit for the solenoid 47, and the latter will draw in its core and operate a punch whose construction and operation is identical with those described. But the continued movement of the pedal and oi the lever ill will disconnect the terminal 45 from the lever and the latter will be cut out at the end a set of punches arranged for retracting each of the downward movement of the pedal,- so that the punch is advanced for an inst-ant only and then retracted. When the pedal is released it will be returned to its normal position, as by a spring 49. The inner elevated end of the pedal will now be lowered, and the terminal portion 43 will engage the lever 40 and swing it down to its former position, but at the intermediate part of the downward movement contact will-be made with the member 45, whereby the circuit is closed and another punch advanced for the short period of time when the contact is made at 45 during this return movement of the pedal. This will cause a different perforation to be made in the roll from that made when the pedal was depressed. From this it will be seen that a certain predetermined punch of the set will cause a hole or mark to be made on the paper only at the instant that the pedal isdepressed; but that a different punch will make a mark in the paper at a different place, and only at the instant the pedal is released. It will be understood that between such two marks on the roll the-pedal has remained depressed and the tone of the instrument made loud or soft during such period. For the other pedal, H, or for any number of pedals, a similar device and pair of punches are provided operating identically in the same manner, where; by a hole or mark is made at the instant the pedal is depressed and another indication when such pedal is released.
